SUMMARY

The discussion centers on calculating the lateral force exerted by a 70,000 lbs truck when braking from a speed of 5 feet per second over a distance of 1 foot. The relevant formula for this calculation is derived from the equation f = m Δv / Δt, where 'm' represents mass, 'Δv' is the change in velocity, and 'Δt' is the time interval. Participants emphasize the importance of attempting to solve the problem independently before seeking assistance, highlighting a pedagogical approach to learning physics concepts related to uniform acceleration.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with the concepts of mass, velocity, and acceleration

A truck weighing 70,000 lbs. is moving at 5 fps. on level ground. The brakes are applied and decelerates over the course of 1 foot. How much lateral force will be be exerting for that 1 second. Need a formula.
Thanks Signman
 
Physics news on Phys.org
f = m \Deltav / \Deltat

plugin values and done.
 
Signman, the formulas should be in your physics textbook, in the section dealing with uniform or constant acceleration. Try looking there.

You'll need to show an attempt at solving the problem before receiving help.

Sourab, please refrain from giving out the equations before people try solving the problem themselves.
